ELECTRIC HEATING APPARATUS.

Application filed Hay 31,

To all whom it may concern:

Be it known that I, EMIL Pmnmrson, a citizen of the United States, residing at the city of New York, borough of the Bronx, Bronx County, in the State of New York, have invented certain new and useful Improvements in Electric Heating Apparatus,.

of which the following is a full, clear, and exact specification.

My invention relates to improvements in electric heating apparatus, and the same has for its object more particularly to provide an apparatus afl'ording a more extensive distribution of the heat than is possible with the usual forms of electric heating apparatus.

Further, said invention has for .its object to provide an electric heating apparatus in which the heat is distributed horizontally in the segment of a circle of large area. Further, said invention has for its object to provide an electricv heating apparatus in which the emitted heat is projected both horizontally and vertically in order to provide a more extensively heated space or zone.

Further, said invention has for its object to provide an electric heating apparatus in which the emitted heat is projected by the joint action of a plurality of separate reflecting members arranged at an angle to one another.

Further, said invention has for its object to provide an electric heating apparatus which shall effectively heat the largest possible space at a minimum expenditure of electric energy.

Other objects will in in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, my invention consists in the novel details of constructiomand in the combination, connection and arrangement-of parts hereinafter more fully described and then pointed out in the claims.

In the accompanyin .drawin Figure 1 is a front view showmg one form of electric heating a paratus constructed according to, and em odying my said invention- 2 is a top view thereof showing hand es in full lines adjusted to carr position, and in broken lines, folded bac shi ping purposes;

Fig. 4 is an end view showin the handles ad usted to serve as leg mem ers to suppoat the apparatus in horizontal position; an

F1g. 5 is an enlarged detail perspective v ew showing one end of the front protective guard and the fastening means therefor.

In said drawings, the apparatus is shown composed of a casing 10 comprising a substantially semi-circular or parabolic vertical wall member 11, preferably made of sheetmetal, such as copper, or other suitable material, having an inner surface polished or otherwise treated to face 12.

Adjacent to the lower edge of said vertical wall member is secured a bottom 13 provided upon its under side with feet 1a which are secured to said bottom by screw 15 passing through the same. 16 denotes a false bottom or partition also preferably made of sheet copper, or other suitable material, having its upper surface polished or other-. wise treated to form a reflecting surface 17. The bottom or partition 16 is secured at its edge to the inner side of the vertical wall member 11 above the bottom13 so as to form a compartment 17 whose front portion is covered by a grill or perforated plate 18 secured to the forward edges of said wall member 11, bottom 13 and false bottom 16.

19 denotes a protective guard comprising a front member 20, and a curved member 20. The said curved member 20 is formed of a U-shaped bar having openings provided in its inner side in which are secured the outer ends of rods 21 whose forward ends are brought together and secured by a rivet 22 and washer 22 to the under side of a projection 23 extending inwardly from the front. member 20 of the guard 19.

24 denotes a guard for the front of the casing 10, which comprises a rectangular frame 25 having rearwardly extending flanges 26 at its opposite side, and a rearwardl extending inner, peripheral flange 27. he horizontal portions of said flange 27; are provided with registering apertures wire which are secured in place by the engagement of their transverse -membe with the inwardly bent projections 29 provided ppon the upper horizontal flange portion 2 I One of the vertical flanges 26 is provided the curved or midway of its ends with an integrallyformed inwardly-extending projectlon 30, and the other of said flanges 26 is provided adjacent to its upper and lower ends with similar projections 30. The said projections 30 are adapted to be receivedby recesses 30 provided in the side wall member 11 adjacent to its front vertical edges in order to hold the front guard 24 detachably secured to said casing 10.

31 denotes an insulating support secured to the false bottom OI p8,Ii3it1OIl"l6 at the focal point of the reflector 12, and up'On said support is secured a suitable resistance element 32 whose terminals extend to an in sulating base 33 secured to the under side of the false bottom 16 to permit of the attachment of said terminals to the conductors' 34. extending through an insulating sleeve 35 in the casing 10.

In order to reinforce the casing 10, the same may be provided with one or more inte ally-formed ribs 10?.

0 form a? convenient means for carrying the apparatus, as well as to provide means for supporting the'same in a horizontal position, the apparatus is provided upon the outer central portion of its vertical wall 11 with a bail 36 whose fiat intermediate portion is soldered or otherwise rigidly secured to the casing 11, and has its ends 37 free and extending outwardly and provided with struck-up longitudinal ribs 38.

39 denotes a handle having its ends secured in sockets 40 of the handle members 41 by a pin 42. The inner ends of the members 41 are pivotally secured by rivets or screws 43 to the ends 37 of the bail 36, and are provided with longitudinal reinforcing ribs 44 whose outer surfaces are adapted to enga e with the recesses formed in the under sides of the ribs 38 on said ends 37 to hold the handle 39 to the carrying position shown in full lines at Figs. 2 and 3.

45 denotes a similar handle having its ends similarly secured in sockets 46 of shorter handle members 47 whose inner ends are also pivotally mounted upon the screws 43. The heads48 at the opposite ends of the pin 49 areadapted to engage with the under or recessed side of the longitudinal reinforcing .ribs 44 of the handle members 41 in order to hold the handle 45 in such position with respect to the handle 39 that the two handles 39, 45 will serve as a single handle, as shown at Figs. 2'and 3.

The operation of the apparatus is largely obvious.

In 0 eration, the greater part of the heat emitte by the element 32, that is to say, the horizontally projected rays, will be received upon and reflected horizontally by parabolic reflector "12, while the downwardly and downwardl -inclined rays will be received upon and re ected upwardly and forwardly by the flat, base reflector 17. Byv this construction and arrangement of reflecting surface a part of the heat will be distributed laterally in the are of a circle of approximately 100 degrees, and vertically in the arc of a circle of approximatel 90 degrees, thereby insuring a combined istribution of heat over a large area or space.

Under ordinary circumstances, the apparatus is intended to be used in the osition illustrated in Figures 1 and 2, in w ich the same rests upon the feet 14. When the current is conducted to the resistance element, the heat will be doubly reflected, i. e., one reflection being produced by the semi-circular or parabolic reflector l2, and the other being produced by the upper surface of the partition or false bottom 16. By this arrangement, the major portion of the heat is projected horizontally outwardl in a flaring direction covering approximately 100, and vertically upwardlfi by the horizontal reflecting surface 16. y this construction and arrangement, a more extensive distribution of the heat is obtained than is possible in the ordinary electric heaters having the usual form of parabolic reflector, or those in which only a single reflector is used.

When it is desired to support the apparatus in a horizontal position, as illus trated in Fig. 4, it merely becomes necessary to adjust the handle 45 by forcing the same outwardly (to the left in Fig. 2) until the portion a engages with the outer surface of the vertical wall 11 of'the apparatus, and then adjust the handle 39 until the portion 6 thereof enga es the outer surface of the casing 11. hen the handle parts have been thus adjusted, they will serve to support the apparatus, as shown in Fig. 4. In this osition, the main portion of the heat r0 need by the apparatus will be projected upwardly by the semicircular or parabolic reflectin surface 12, and a smaller or less amount 0 the heat pro'ected horizontally outwardly by the re ecti surface 16 formed by the base or partition of the casing. In this osition, the apparatus may be employed or toasting bread, or the like, or for cooking or heatin any article which can be upon the guar 24 When the apparatus to be packed for shi ment, it merely becomes necessary to 0 d the shorter handle 45 to the left, as indicated in. Fig. 2, and the longer handle 39 to the right.
